Alcohol

Worst

Alcohol relaxes the body, but, unfortunately, it also relaxes the esophageal sphincter. This can lead to acid reflux or heartburn.

Drinking also can inflame the stomach lining, impairing certain enzymes and preventing nutrients from being absorbed, Anderson says. Too much alcohol can cause diarrhea and cramping, but unless you have a gastrointestinal disorder, moderate amounts of alcohol shouldn't irritate the digestive tract.

Guidelines suggest no more than two drinks a day for men and one for women.
